Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.Explained below relates to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they are only with the most appended
The example of the apparatus and method that some aspects that described in detail in claims, the disclosure are consistent.
Fig. 1 is the flow chart according to a kind of charging method shown in an exemplary embodiment, as it is shown in figure 1, this charging side
Method can apply to, in charger (such as charger), comprise the following steps.
In step s 11, in battery charging process to be charged, obtain the voltage of battery to be charged；
In step s 12, when the voltage of battery to be charged reaches predetermined voltage threshold, it is reduced to battery to be charged charging
The charging current of the first charging module so that battery to be charged keeps the constant-current charging phase in charging process.
Battery to be charged can be independent battery, then charger can be charged directly to independent battery,
Or battery to be charged can also be mounted in the battery in electronic equipment, is such as integrated in the battery in mobile phone, then charging
Equipment can be connected with the electronic equipment being provided with battery and then charge to battery to be charged.
During charging to battery to be charged, charger can obtain the voltage of battery to be charged in real time, right
In the mode obtained, disclosure embodiment does not limits.Such as, charger can check the electricity of the battery charged voluntarily
It is pressed into and obtains the voltage that detects, or for example, it is possible to detected voltage by the electronic equipment being provided with battery to be charged and send out again
Give charger, etc..
The charging module included by charger can be charged to battery to be charged, it is believed that the disclosure is implemented
Charging module (including the first charging module and the second charging module etc. hereafter) in example is that a kind of logic function divides,
Realization in actual physics meaning can be such as charging chip and the charging circuit being connected with this charging chip, etc..This
Charger in open embodiment can have one or more charging module, disclosure embodiment to be not construed as limiting this.
Generally, charging process can include three phases: when the voltage of battery to be charged is less, such as less than 3V, now
The electricity of battery to be charged is less, in order to protect battery, less electric current can be used to charge to battery to be charged, and this stage claims
For the trickle charge stage；After the voltage of battery to be charged increases to certain value, after such as voltage rises to 3V, phase can be used
Charging to battery to be charged in bigger electric current, to improve the speed of charging, this stage is referred to as constant-current charging phase；In constant current
Charging stage, the voltage of battery to be charged can continue to increase, after reaching certain magnitude of voltage, after such as reaching 4.4V, in order to
Preventing from overcharging, be basically unchanged by holding voltage, the mode that electric current is gradually reduced is charged, and this stage is referred to as constant-voltage charge rank
Section.
To in battery charging process to be charged, if the voltage of battery to be charged is relatively low, at battery the most to be charged
In the trickle charge stage, then the charging module that charger can be used to include exports less charging current to electricity to be charged
Charge in pond, such as by the charging current of the first charging module output 0.2A, when charger includes multiple charging module, this
Time can use any one charging module therein less charging current of output.Along with the continuation of charging, battery to be charged enters
Enter constant-current charging phase, then bigger electric current can be used to charge to battery to be charged, such as defeated by the first charging module
Go out the charging current of 2A, when charger includes multiple charging module, now can also use multiple charging modules simultaneously
Charge in a parallel fashion battery to be charged.
Predetermined voltage threshold can be used to determine that battery to be charged is entered constant voltage charging phase by constant-current charging phase
Critical voltage value, when the voltage of battery to be charged is more than or equal to predetermined voltage threshold, it is believed that battery to be charged is in
Constant voltage charging phase in charging process, is how many for predetermined voltage threshold actually, and disclosure embodiment is not construed as limiting, and presets
Voltage threshold can be different according to the difference of the specification of battery to be charged, such as, for certain specification battery to be charged and
Speech, predetermined voltage threshold is 4.4V, etc..
Optionally, after reducing the charging current of the first charging module and the second charging module respectively, the first charging mould
When the charging current sum of block and the second charging module is not less than predetermined current threshold, can again perform to obtain battery to be charged
Voltage, and when the voltage of battery to be charged reaches predetermined voltage threshold, be reduced to the first of battery to be charged charging and fill
The step of the charging current of electricity module.
It is to say, when battery to be charged is in constant-current charging phase, the first charging module can be with constant charging
Electric current is that battery to be charged is charged, and the voltage of battery the most to be charged gradually rises, when the voltage of battery to be charged reaches
During predetermined voltage threshold, can reduce the charging current of the first charging module, the voltage of corresponding battery to be charged can be reduced to
Below predetermined voltage threshold, battery to be charged keeps constant-current charging phase, and the first charging module is with the charged electrical after reducing
Stream continues to be battery to be charged charging in the way of constant current.Certainly, the first charging module is waited to fill with the charging current after reducing
After electricity battery is charged, cell voltage to be charged can increase again, when the voltage of battery to be charged reaches predeterminated voltage again
During threshold value, again can reduce on the basis of the charging current of the first charging module value after upper once reduction so that treat
Rechargeable battery turns again to constant-current charging phase, i.e. during charging to battery to be charged, at the first charging module and the
The charging current sum of two charging modules, not less than in the case of predetermined current threshold, can repeat above-mentioned steps S11-step
Rapid S12.
Such as, the initial voltage of battery to be charged is 3V, can charge it at this voltage in the way of directly with constant current,
Such as, by the first charging module with the charging current of 2A be its charging, when the voltage of battery to be charged reaches predeterminated voltage threshold
During value 4.2V, the charging current of the first charging module can be reduced, be such as reduced to 1.5A, the voltage meeting of battery the most to be charged
Drop to below 4.2V, then the first charging module can be continued through and charge to battery to be charged with the charging current of 1.5A.
By the way of above, the battery to be charged that extends that can be relative is in the time of constant-current charging phase, Jin Erjia
Charging quickly speed, saves the time that charging expends, enhances Consumer's Experience.
Optionally, it is reduced to the charging current of the first charging module of battery to be charged charging, can include reducing by first
The charging current of charging module, and reduce with the first charging module be jointly battery to be charged charge the second charging module
Charging current.
It is to say, in the case of charger includes more than one charging module, such as charger includes first
Charging module and the second charging module, can charge first after the voltage of battery to be charged reaches predetermined voltage threshold respectively
The charging current of module and the second charging module all reduces, then uses simultaneously and reduce the first charging module after charging current and the
Two charging modules charge to battery to be charged.
Visible, disclosure embodiment have employed be continuing with reducing after reaching predetermined voltage threshold after charging current the
One charging module and the second charging module give the mode of battery to be charged charging rather than after reaching predetermined voltage threshold simultaneously
Close one of them charging module, only use the mode that a charging module is full of until electricity.This way it is possible to avoid reaching
After predetermined voltage threshold, the phenomenon that the heating that only is charged causing by a charging module is serious, to charging module and
Charger serves the effect of protection, meanwhile, battery to be charged can be more in constant-current charging phase, filling of quickening
Electricity speed, improves Consumer's Experience.
Optionally, for how on earth reducing the first charging module and the charging current of the second charging module, the disclosure is real
Execute example to be not construed as limiting, for example, it is possible to respectively by the first charging module and the second charging module on the basis of current charging current
Current value is reduced according to the first ratio.
Value for the first ratio is how many actually, and disclosure embodiment is not construed as limiting, and the first ratio can be that charging sets
For set when dispatching from the factory, first ratio that such as can set is as 20%, then such as, the first charging module and the second charging mould
The current charging current of block is 2A, after reducing current value according to the first ratio, the first charging module and the second charging module
Charging current all reduces to 1.6A, etc..By such mode, so that battery to be charged reaches after predetermined voltage threshold again
The secondary constant-current charging phase that returns to is charged, and improves the speed of charging, can utilize multiple charging mould the most fully simultaneously
Block, it is to avoid load imbalance and the generation of bad phenomenon of dispelling the heat.
Optionally, after reducing the charging current of the first charging module and the second charging module respectively, the first charging mould
The charging current sum of block and the second charging module is less than predetermined current threshold, then can close the second charging module, pass through
First charging module charges to battery to be charged.
Voltage at battery to be charged repeatedly reaches predetermined voltage threshold and repeatedly reduces the first charging module and second and fill
After the charging current of electricity module, after the most repeatedly circulation performs step S11-step S12, the first charging module and second
The charging current of charging module is all reduced to less value (the such as first charging module and the charging current of the second charging module
Sum has been less than predetermined current threshold), the electricity of battery the most to be charged may be already close to full charge amount, battery to be charged
Constant voltage charging phase can be entered, then one of them charging module can be closed, such as close the second charging module, use
First charging module charges to battery to be charged, until battery to be charged is full of.
For example, it is possible to set predetermined current threshold as 0.5A, the first charging module and the initial charge of the second charging module
Electric current is 2A, and the first ratio every time reducing charging current is 20%, reduces the first charging module and the second charging at the 10th time
After the charging current of module, the charging current sum of the first charging module and the second charging module is 0.42A, less than predetermined current
Threshold value, then can close the second charging module, uses the first charging module to charge to battery to be charged in the way of constant voltage.
By the way of above, battery to be charged can be extended as much as possible and be in the duration of constant-current charging phase, simultaneously
Shorten battery to be charged as much as possible and be in the duration of constant voltage charging phase, accelerate charger and charge to battery to be charged
Speed, shorten the time reached needed for full charge amount.
Optionally, after charging to battery to be charged by the first charging module, the first charging mould can detected
When the electric current of block output is less than or equal to charge cutoff electric current, closes the first charging module, complete to treat the charging of rechargeable battery.
Closing the second charging module, when using the first charging module to charge to battery to be charged in the way of constant voltage,
The electric current of the output of the first charging module can be gradually reduced, when the electric current of the first charging module output is reduced to less than or equal to fill
During electricity cut-off current, it is believed that battery to be charged has reached full charge amount, now can close the first charging module, treat
The charging process of rechargeable battery the most just completes.For detecting the mode of the value of the electric current of the first charging module output, the disclosure
Embodiment is not construed as limiting, and such as directly can be detected by charger, or can also be to be charged by being provided with
The electronic equipment of battery detects, then the current value detected is sent to charger, etc..
By the way of above, the first charging module can be closed, it is to avoid treat rechargeable battery after determining charging complete
Cause overcharge, serve the effect protecting battery to be charged, also save electric energy simultaneously.
In order to the technical scheme of the disclosure is better described, below the embodiment complete with is illustrated.
Such as, the initial voltage of battery to be charged is that (such as cell voltage can use constant current when more than or equal to 3V to 3V
Charging modes), predetermined voltage threshold is 4.4V, and predetermined current threshold is 0.5A, and charge cutoff electric current is 0.1A, charging current
The first ratio reduced is 20%.
Charging starts, and the charging current of the first charging module and the second charging module is 2A, i.e. with the charging of 4A altogether
Electric current is that battery to be charged is charged.Along with the continuation of charging, the voltage of battery to be charged is gradually increasing by initial 3V, when
When reaching 4.4V for the first time, the charging current of the first charging module and the second charging module reduces by 20% respectively, i.e. the first charging
The charging current of module and the second charging module all reduces to 1.6A, and the voltage of battery the most to be charged is less than 4.4V, continues with always
The charging current of 3.2A is battery to be charged charging altogether.Along with the continuation charging of the charging current of 3.2A, the electricity of battery to be charged
Pressure is gradually increasing, during until second time reaches 4.4V, again by the charged electrical flow point of the first charging module and the second charging module
Not reducing by 20%, reduced to 1.28A by 1.6A the most respectively, now the voltage of rechargeable battery is again below 4.4V, continues with always
The charging current of 2.56A is battery to be charged charging altogether, and during until the voltage regulation of battery to be charged is raised to 4.4V ten times, first fills
Electricity module all falls below 0.21A with the charging current of the second charging module, and total charging current is 0.42A, less than predetermined current
Threshold value 0.5A, then can close the second charging module, by the electric current of the first charging module output 0.42A, in the way of constant voltage
It is charged for battery to be charged.In constant voltage charging phase, the electric current of the first charging module output is gradually reduced, and is being reduced to
During charge cutoff electric current 0.1A, close the first charging module, complete to treat the charging of rechargeable battery.
